I needed to add the hard disks in the BIOS to make them visible - one of the annoying aspects of these Dell machines. First on Tux02 I cheched the borg backups to see if we have a recent copy of MariaDB, GN2 etc. The DB is from 2 days ago and the genotypes of GN2 are a week old (because of a permission problem). I'll add a copy by hand of both - an opportunity to test the new 10Gbs router.
Before rebooting
On Tux02:
On both:
We can add a lot of SATA disks. To configure run racadm and set serial settings
: racadm set iDRAC.Serial.Enable 1
Dump everything
: racdump
: get nic.nicconfig.4
: hwinventory
Reboot
: racadm>>serveraction powercycle
: racadm>>serveraction hardreset
: racadm>>serveraction powerstatus
: racadm>>connect com2
racadm>>
config -g cfgSerial -o cfgSerialBaudRate 115200
config -g cfgSerial -o cfgSerialCom2RedirEnable 1
config -g cfgSerial -o cfgSerialSshEnable 1
config -g cfgIpmiSol -o cfgIpmiSolEnable 1
config -g cfgIpmiSol -o cfgIpmiSolBaudRate 115200
get iDRAC.serial
Now you should see the menu in
: console com2
On tux02 eno2d1 is the 10Gbs network interface. Unfortunately I can't get it to connect at 10Gbs with Tux01 because the latter is using that port for the outside world.
Playing with 10Gbs on Tux01 sent the hardware in a tail spin, what to think of this solution on
bnxt_en 0000:01:00.1 (unnamed net_device) (uninitialized): Error (timeout: 500015) msg {0x0 0x0} len:0
Solution was to power down the server(s) and *remove* power cords for 5 minutes.
The Linux kernel shows some fixes that are not on Tux01 yet

In our case a simple reboot worked, fortunately.
